, Application filed August 12, 1912. Serial No. 714,636.

To all whom it may concern Be it known that I,.Bnoonn1on HASKELL, acitizen of the United States, residing at Franklin, in the county ofVenango and State of Pennsylvania, have invented certain new and usefulImprovements in Telegraph- Poles and the like, of which the following isa specification.

The present invention has to do with the construction of metallic polesdesigned especially for telegraphs or otheroverhead wire supports, andparticularly to a type of such pole wherein a series of upright legs areheld inproper spaced apart relation by a series of transverse bandssecured thereto at proper intervals.

The matters of invention in the present instancerelate to aconstructlonwhereby I1 ples of my invention; Fig. 2 is a transversesectionon an enlarged scale, the same showing a transverseband andlocking devices in elevation; Fig. 3 is a section on line 2-2 of Fig. 2;Fig. 4 is an enlarged plan View of the locking devices and corner oftransverse band; Fig. 5 represents a perspective view of severalelements comprising means for locking uprights to the transverse bands;and Fig. 6 is a section similar to that of Fig. 2 of a modification ofthe transverse band.

The uprights or longitudinal members 1 are preferably four in number andas shown are formed into L-shape in cross section from bar stock. Thetransverse bands 2 i are likewise formed of plate or sheet material ofsuitable Width and preferably square, as shown, and are provided withpockets at the corners to receive the uprights 1. These pockets may beformed from the stock of the band itself and proper straps 3 may beemployed to close the mouths of said pockets. The transverse bands however, instead of being continuous, may be made of two U-shapedsectionsQ, and 2 held together by riveting the V-shaped straps 3*.and 3as shown in Fig. 6. The straps 3 and 5 in this casenot only form theinnerside ofthe corner pockets but at the same time means for. securelybinding the sections of thetransverse bands and thus avoids weldingwithout increasing. the number of rivets.

The, manner of securely lockingand fastening the uprights to thetransverscbands is effected as follows: Each of the transverse bands isprovided at each side and near the corners with a recess or depression4, extending outwardly. Filling blocks 5 and 6 are fashioned tosubstantially fill the aforesaid corner pockets, the same having intheir abutting faces complementary portions of a recess 7, to receive awedge block 8,which is inserted so as to exert its principal Wedgingaction in separating the blocks and pressing the same against the sidesof the uprights 1. Theinncr sides of said wedging blocks 5 and 6 areformed with a wedg'ing bulge 9 which, as will be clear when the blocksare forced home, coact with the strap 3, and cause the bulge sections 9,9, to force the corresponding sections of the upright 1 into therecesses or depressions 4: of the transverse bands,as shown in Figs. 3and 4.

The filler blocks may be made as shown, so as to slightly taper from thetop to bottom in. order to rest in the corner pockets against the innerside of straps 3, as shown in Fig. 4.

From the foregoing disclosure it Will be seen that I have provided meanswhereby the uprights and transverse bands are strongly and effectivelyclamped together by a few parts, and. the same can be readily assembledor disconnected without :destroying their ability to be used over again.

While I have shown the sections comprising the transverse bands andstraps as riveted together, any otherexpedient could be used as boltingor welding.

What I claim is 1. A knockdown pole comprising up rights, transversebands having pockets to receive said uprights, said bands havingrecessesor depressions extending outwardly at their pocket sections, strapssecured to said bands adjacent said pockets, plural r'e movable fillingmembers for each pocket having permanent bulged sections orprojectionscorresponding to the recesses or depressions in the bands, andremovablemeans to expand the filling members.

2. A knock down pole comprising up- I their pocket sections,- strapssecured to said bands adjacent said pockets, ,tWo' removable fillingmembers for each pocket, each havingj a permanent-bulged section orprojection corresponding to the recessor depression in. the bands, and-aremovable Wedge to expand the filling members. v

3. A knockdown po1e=- comprising upright's, transverse bands each ofWhich'con- 'sists of two angular shaped pieces forming inner pockets toreceive uprights and hands, and means abutting against said uphavingtheir free ends adjacent each other, tWo angular shaped straps'on theinner sides of thetransverse bands with the free ends of said strapsadjacent each other, and connected to the center sections of said bandsand the; center sections of the straps connected to the free ends of thetransverse rights and straps for holding said uprights in the pockets ofthe band's 1 In testimony whereof. I aflix my signature in presence oftwo Witnesses BRoDERioK HASKELL Vitnes'ses:
